Description

Technical Field

[0001] The utility model relates to the technical field of film lamination, in particular to a film lamination device. Background Art

[0002] Artificial stone and other boards usually need to be coated before leaving the factory to prevent the boards from being hit, scratched or contaminated during stacking, transportation and paving. Especially during the paving process, a large amount of sand will cause great damage to the surface of the board. And the film is usually torn off after the board is laid, inspected and cleaned.

[0003] Laminating artificial stone and other boards usually requires a laminating machine, which can efficiently and automatically stick the film to the surface of the board. Common laminating machines on the market usually include a film placing cylinder, a tensioning roller, a film pressing roller and a film cutting device, wherein the film placing cylinder, the tensioning roller and the film pressing roller are arranged in sequence from top to bottom, and the film cutting device is arranged behind the film pressing roller. When laminating, the film roll is placed behind the film placing cylinder, and then the film material on the film placing cylinder is pulled out. After passing through the tensioning roller, the film material enters the bottom end of the film pressing roller, and the film material is applied to the upper surface of the board by the film pressing roller. After the entire board passes through the film pressing roller, the film is cut off by the film cutting device, that is, the lamination of the current board is completed, and the film pressing roller continues to apply film to the next board.

[0004] Although the above-mentioned laminating machine can quickly attach the film to the surface of the plate, there are still some problems. In the non-continuous laminating process, after the laminating roller completes the laminating of the previous plate, it is necessary to wait for the next plate to move to the lowest end of the laminating roller and contact the laminating roller before laminating the next plate. Since the film cutting device is arranged behind the laminating roller, and in order not to affect the normal operation of the film cutting device and the laminating roller, a certain interval is usually provided between the film cutting device and the laminating roller. This will cause the section of film material between the film cutting device and the lowest end of the laminating roller to not be attached to the surface of the next plate when laminating the next plate, resulting in a section of extra film material on one side of the next plate, and as the distance between the film cutting device and the lowest end of the laminating roller increases, the extra film material on one side of the plate will be longer, which is not conducive to the subsequent work on the plate. Therefore, it is urgent to develop a laminating device that has a short extra film material on the side of the plate after laminating. Utility Model Content

[0043] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, the meaning of "plurality" is more than two.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] The laminating device of this embodiment includes a frame 1, a film frame 2, a conveying device 3 and a laminating device 4, wherein the film frame 2 is installed on the top of the frame 1, the laminating device 4 is installed in the frame 1, and the laminating device 4 is located below the film frame 2, the conveying device 3 is arranged on the frame 1 and is fixedly connected to the frame 1, and the conveying device 3 is located below the laminating device 4, the film frame 2 is used to place a film material 5, and the conveying device 3 is used to transport a plate 6;

[0046] The film coating device 4 includes a roller group, a film collecting mechanism 44, a first film pressing mechanism 45 and a film cutting mechanism 46. The roller group is installed on the frame 1; the film collecting mechanism 44 is installed horizontally on the frame 1, and the telescopic end of the film collecting mechanism 44 is connected to the roller group. The film collecting mechanism 44 is used to tension the roller group when collecting the film, so that the excess film material 5 under the first film pressing mechanism 45 can be recovered;

[0047] The first laminating mechanism 45 is disposed below the roller group, and is used to laminate the film 5 onto the surface of the plate 6;

[0048] The film cutting mechanism 46 is installed on the frame 1 in a lifting manner, and is located behind the first film pressing mechanism 45 . The film cutting mechanism 46 is used to cut the film material 5 .

[0049] It is worth noting that when the coating device of the present technical solution is used to coat the sheet 6, the film material 5 pulled out from the film frame 2 passes through the roller group in sequence and is placed at the bottom of the first film pressing mechanism 45. After the conveying device 3 conveys the sheet 6 to the bottom of the first film pressing mechanism 45, the first film pressing mechanism 45 presses the film material 5 to the surface of the sheet 6, and the film material 5 is attached to the surface of the sheet 6 through the film material 5. After the entire sheet 6 is coated, the film material is cut by the film cutting mechanism 46, thereby completing the coating of the sheet. The coating device of the present technical solution includes a film collecting mechanism 44, which is connected to the roller group. The film collecting mechanism 44 is used to tension the roller group when collecting the film, so that the excess film material 5 under the first film pressing mechanism 45 is retracted, so that when the next sheet is coated, it can avoid that there is too much excess film material at the end of the next sheet that is first coated.

[0050] Specifically, after the laminating equipment using the present technical solution has completed laminating the previous plate, the roller group can be tensioned through the film collecting mechanism 44, and the excess film material 5 under the first film pressing mechanism 45 can be retracted. When laminating the next plate, it can effectively prevent the edge of the plate from having an excessively long film edge, and by controlling the extended length of the telescopic end of the film collecting mechanism 44, the retracted length of the film material 5 can be controlled, thereby controlling the length of the excess film material at the edge of the plate to be within 1 cm.

[0051] Preferably, in an embodiment of the present utility model, the conveying device 3 is a roller conveyor, which can convey the plate 6 so that the plate 6 moves on the conveying device 3 .

[0052] Preferably, the film frame 2 includes a film frame base and a film placing cylinder. After the film placing cylinder passes through the film roll, the film roll is placed on the film frame base. The film frame base is provided with a slot that matches the film placing cylinder, so that both ends of the film placing cylinder can be placed in the slot, thereby placing the film roll on the film frame 2, and the film pulled out of the film roll is the film material 5.

[0053] Further explanation, the roller group includes a film-receiving roller 41, a tensioning roller 42 and a smoothing roller 43, and the film-receiving roller 41, the tensioning roller 42 and the smoothing roller 43 are all installed on the frame, and the film-receiving roller 41, the tensioning roller 42 and the smoothing roller 43 are arranged in sequence from top to bottom;

[0054] The telescopic end of the film collecting mechanism 44 is connected to the tensioning roller 42 , and the film collecting mechanism 44 is used to drive the tensioning roller 42 to reciprocate along the length direction of the conveying device 3 .

[0055] It is worth noting that when the laminating device of the present technical solution is used to laminat the sheet 6, the film material 5 pulled out from the film frame 2 passes through the film collection roller 41, the tensioning roller 42 and the smoothing roller 43 in sequence, and is placed at the bottom of the first film pressing roller 451. After the conveyor 3 conveys the sheet 6 to the bottom of the first film pressing roller 451, the first film pressing roller 451 descends and presses to the surface of the sheet 6, and the film material 5 is attached to the surface of the sheet 6 by the first film pressing roller 451. After the entire sheet 6 is laminatated, the film material is cut by the film cutting mechanism 46, thereby completing the lamination of the sheet. The laminating device of the present technical solution includes a film collection mechanism 44, and the telescopic end of the film collection mechanism 44 is connected to the tensioning roller 42, so that the film collection mechanism 44 can drive the tensioning roller 42 to reciprocate along the length direction of the conveyor 3. When the laminating equipment using the present technical solution has completed laminating the previous plate, the film collecting mechanism 44 can drive the tensioning roller 42 to move toward the side away from the smoothing roller 43, so that the film material 5 moves toward the side away from the smoothing roller 43, thereby retracting the excess film material 5 between the film cutting mechanism 46 and the bottom end of the first film pressing roller 451, and retracting the film material 5 to a position close to the bottom end of the first film pressing roller 451. When laminating the next plate, it can effectively prevent the edge of the plate from having an excessively long film edge, and by controlling the extended length of the telescopic end of the film collecting mechanism 44, the retracted length of the film material 5 can be controlled, so that the length of the excess film material at the edge of the plate can be controlled within 1 cm.

[0056] For further explanation, mounting plates 11 are provided on both sides of the frame 1, and the film collecting mechanism 44 includes two film collecting components, which are respectively installed transversely on the mounting plates 11 on both sides of the frame 1, and both ends of the tensioning roller 42 are respectively connected to the telescopic ends of the two film collecting components.

[0057] Based on the fact that the two ends of the tensioning roller 42 are respectively connected to the telescopic ends of the two film collecting assemblies, the tensioning roller 42 can be driven by the two film collecting assemblies to smoothly reciprocate along the length direction of the conveying device 3, thereby recovering the excess film material at the bottom end of the first film pressing roller 451, ensuring that when the next plate is coated, the excess film material on the edge of the plate is shorter and will not affect the subsequent work of the plate.

[0058] To further illustrate, the film collection assembly includes a driving cylinder 441, a slide rail 442, a sliding seat 443, a connecting plate 444 and a fixing plate 445;

[0059] The fixing plate 445 is transversely mounted on the mounting plate 11, the slide rail 442 is transversely mounted on the fixing plate 445, the sliding seat 443 is slidably connected to the slide rail 442, and the side of the sliding seat 443 away from the slide rail 442 is fixedly connected to the connecting plate 444;

[0060] The fixed end of the driving cylinder 441 is fixedly mounted on the mounting plate 11 , the telescopic end of the driving cylinder 441 is connected to the connecting plate 444 , the end of the tensioning roller 4 is fixedly connected to the connecting plate 444 , and the driving cylinder 441 is used to drive the connecting plate 444 to reciprocate along the slide rail 442 .

[0061] It is worth noting that in one embodiment of the present invention, the two ends of the tensioning roller 42 are respectively installed on the connecting plates 444 of the two film collecting assemblies located on the left and right sides of the frame 1 through bearing seats, that is, the two ends of the tensioning roller 42 are respectively installed on the connecting plates 444 of different film collecting assemblies, and through the driving action of the driving cylinder 441, the connecting plate 444 can reciprocate along the slide rail 442, thereby driving the tensioning roller 42 to reciprocate along the slide rail 442 to achieve the film collecting effect.

[0062] Further explanation, the film coating device 4 also includes two lifting mechanisms 48 for driving the film cutting mechanism 46 to rise and fall, and the two lifting mechanisms 48 are respectively vertically installed on both sides of the frame 1;

[0063] The film cutting mechanism 46 includes a heating wire 461 and a tensioning assembly 462 . The two ends of the heating wire 461 are respectively connected to the tensioning assembly 462 . The telescopic end of the lifting mechanism 48 is connected to the tensioning assembly 462 .

[0064] It is worth noting that the two ends of the heating wire 461 of the present technical solution are respectively connected to the telescopic end of the lifting mechanism 48 through the tensioning assembly 462. The two lifting mechanisms 48 can drive the two tensioning assemblies 462 to move back and forth in the vertical direction, thereby driving the heating wire 461 to move up and down in the vertical direction. When the heating wire 461 moves downward, it will contact the film material 5. The heating wire 461 with a certain temperature can melt the film material 5. When the film material 5 is melted, the telescopic end of the lifting mechanism 48 is retracted, driving the heating wire 461 to move upward, thereby preventing the film cutting mechanism 46 from affecting the movement of the rear end plate.

[0065] Preferably, in an embodiment of the present technical solution, mounting beams 12 are respectively provided on both sides of the frame 1, and two lifting mechanisms 48 are respectively vertically mounted on the mounting beams 12 on both sides of the frame 1 through L-shaped mounting plates.

[0066] Preferably, the lifting mechanism 48 is a cylinder, the telescopic end of the cylinder is connected to the tensioning assembly 462, and the cylinder drives the tensioning assembly 462 to move up and down, thereby driving the heating wire 461 to move up and down, thereby achieving the effect of cutting the film material.

[0067] More preferably, the tensioning assembly 462 includes a fixing rod 4621 and a ceramic head seat 4622, the end of the heating wire 461 is fixedly connected to the fixing rod 4621, the fixing rod 4621 is inserted into the interior of the ceramic head seat 4622, and the telescopic end of the lifting mechanism 48 is fixedly connected to the ceramic head seat 4622. When the telescopic end of the lifting mechanism 48 is extended or retracted, it can drive the tensioning assembly 462 to move downward or upward, thereby driving the heating wire 461 to move downward or upward. When the heating wire 461 moves downward, it contacts the film material, so that the film material is melted by the heating wire 461 with a certain temperature, thereby achieving the effect of cutting off the film material 5.

[0068] To further illustrate, the first lamination mechanism 45 includes a first lamination roller 451 , a driving assembly 452 , and a mounting seat 453 ;

[0069] The first laminating roller 451 is installed on the frame in a lifting manner, and the first laminating roller 451 is located below the leveling roller 43;

[0070] Both ends of the first laminating roller 451 are respectively connected to mounting seats 453 , and each mounting seat 453 is respectively provided with a driving component 452 for driving the mounting seat 453 to reciprocate along the height direction of the frame 1 ; the driving component 452 is installed on the frame 1 , and the telescopic end of the driving component 452 is connected to the mounting seat 453 .

[0071] It is worth noting that the two ends of the first laminating roller 451 of the present technical solution are respectively connected with mounting seats 453, which are driven by the driving assembly 452 to reciprocate along the height direction of the frame 1, and can drive the first laminating roller 451 to reciprocate along the height direction of the frame 1. During lamination, when the sheet 6 moves to the bottom of the first laminating roller 451, the first laminating roller 451 is driven by the driving assembly 452 to move downward, so that the first laminating roller 451 presses the sheet 6, thereby applying the film material to the surface of the sheet 6; when the entire sheet 6 passes through the first laminating roller 451 and the film material is melted by the heating wire 461, the first laminating roller 451 is driven by the driving assembly 452 to move upward, ready to laminarize the next sheet.

[0072] Preferably, in one embodiment of the present invention, the driving component 452 is a cylinder.

[0073] To further illustrate, the first laminating mechanism 45 further includes a guide plate 454, one side of which is fixedly connected to the frame 1;

[0074] Sliding grooves matched with the guide plate 454 are respectively provided on both sides of the mounting seat 453, and the mounting seat 453 is slidably connected with the guide plate 454 through the sliding grooves.

[0075] In the present technical solution, a guide plate 454 is provided, and the two sides of the mounting seat 453 are slidably connected to the guide plate 454 through sliding grooves respectively. The guide plate 454 can play a guiding role, so that the mounting seat 453 can move along the guide plate 454 when moving, so that the first film pressing roller 451 can move up and down along the guide plate 454, so that the guide plate 454 can move in a directional manner and the moving process is more stable without shaking.

[0076] The laminating device 4 further includes a second laminating mechanism 49, which is mounted on the frame 1 and located behind the first laminating mechanism 45; the second laminating mechanism 49 includes a second laminating roller 491, which is mounted on the frame 1 in a lifting manner;

[0078] This technical solution can achieve a better laminating effect by setting up two laminating mechanisms. Specifically, the first laminating roller 451 and the second laminating roller 491 are arranged above the conveying device 3 along the conveying direction of the conveying device 3, and the second laminating roller 491 is located behind the first laminating roller 451. When laminating, the film material 5 pulled out by the film frame 2 passes through the film receiving roller 41, the tensioning roller 42 and the leveling roller 43 in sequence, and is placed at the bottom of the first laminating roller 451. The plate 6 first passes through the first laminating roller 451 located at the front end of the frame 1. When the end of the plate 6 moves to the first laminating roller 451, the first laminating roller 451 moves downward to press the plate 6 and laminarize the plate. When the end of the plate 6 continues to move to the second laminating roller 491 located at the rear end of the frame 1, the second laminating roller 491 moves downward to press on the surface of the already laminating plate 6, so that the film material is repeatedly rolled once, so as to better adhere to the surface of the plate 6 and achieve a better laminating effect.

[0079] Specifically, the structural composition of the second film pressing mechanism 49 in the present technical solution is the same as that of the first film pressing mechanism 45. In addition to the second film pressing roller 491, the second film pressing mechanism also includes a driving component, a mounting seat and a guide plate for driving the second film pressing roller 491 to achieve a lifting effect. The driving component, the mounting seat and the guide plate in the second film pressing mechanism 49 are the same as the driving component, the mounting seat and the guide plate in the first film pressing mechanism 45, and the installation method of the second film pressing roller 491 is the same as that of the first film pressing roller 451.

[0080] Further explanation, the laminating device 4 further includes an air blowing pipe 47, which is installed on the frame 1 and is located in front of the first laminating roller 451;

[0081] The air blowing pipe 47 is provided with an air blowing hole, and the air outlet direction of the air blowing hole is toward the first lamination roller 451 .

[0082] It is worth mentioning that the technical solution sets an air blowing pipe 47 in front of the first laminating roller 451, and the air outlet direction of the air hole is toward the first laminating roller 451. During lamination, air is blown through the air blowing pipe 47 to make the non-coated side of the film material 5 close to the roller surface of the first laminating roller 451, so that the starting point of the lamination can be further controlled, thereby obtaining a better lamination effect, and at the same time, it can effectively reduce the bubbles on the surface of the plate after lamination.

[0083] To further explain, the laminating device 4 further includes a guide roller 46 , which is mounted on the frame 1 , and is located below the leveling roller 43 and in front of the leveling roller 43 .

[0084] The present technical solution further includes a guide roller 46 in the laminating device 4, and the guide roller 46 can play a guiding role.

[0085] Preferably, the guide roller 46 is made of Teflon (ie polytetrafluoroethylene). Teflon has a non-adhesive property and almost all substances do not adhere to Teflon, thereby preventing the guide roller 46 and the film material from adhering to each other.

[0086] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
